Rayna and Robin are best friends. They decided to go on vacation together to Jamaica. They agreed that Rayna would make all of the travel arrangements and pay for them, and then Robin would reimburse Rayna for her share. Rayna put the agreement in writing and included details of all of the expenses for which Robin was to reimburse Rayna. Robin, excited about the trip and trusting Rayna, signed the agreement without reading it. She was shocked when Rayna later asked for a check for $5324 for herportion of the trip. Of that amount, $3244 was for First Class airfare. Robin was upset, as she had no idea that Rayna purchased First Class airfare and would have preferred to fly coach. Robin refused to pay for the airfare. Rayna sued Robin. Who will win?
